Gemini 2 has a more in-depth and faster scanning capability for duplicate items. It can quickly find out the same pictures, fonts, or other configuration files hidden in various libraries. It can also search for files with different file names and suffixes but the same contents. Besides, Gemini 2 can scan the repeated songs and picture files in iTunes.app and Photos.app.
Gemini 2 scanning results provide very detailed information. Users can preview the file content, play the audio, view the pictures, read the text directly, and locate the file directory. However, the "similar files" listed in the software are not reliable. For example, the file names in a set of audiobooks are organized by "filename + numerical order," while Gemini lists these files as duplicate items, not very smart.
